Film image input method

Abstract

A roll of developed still photographic film feeds toward an image capturing part. The image capturing part captures the image data of plural frames. An index image, which is composed of plural frames, is made in accordance with the captured image data of plural frames, and the index image is displayed on a display. When the index image is displayed, the format information relating to an aspect ratio of each frame, which is recorded in the film, is read. An image processing conforming to the format information of each frame is executed in accordance with the read format information, so that the aspect ratio of each frame in the index image can be seen. Only an image area, which is required for display and printing, is read according to the format information relating to the aspect ratio of each frame. As a result, the pixels of the line sensor can be used effectively.

       9. The film image input method according to claim 5, wherein said mask covers upper and lower or right and left areas of an image in said predetermined exposure area, and when an instruction is entered to move an area of validity other than said mask up and down or right and left, a ratio of sizes of the upper and lower or right and left areas of said mask is changed conforming to said instruction, so that said area of validity is moved up and down or right and left. 
     
     
       10. The film image input method according to claim 1, wherein said image processing conforming to said format information is executed in such a manner that only an image in an area of validity according to the aspect ratio of each frame in accordance with said format information. 
     
     
       11. The film image input method according to claim 2, wherein said image processing conforming to said format information is executed in such a manner that only an image in an area of validity according to the aspect ratio of each frame in accordance with said format information. 
     
     
       12. The film image input method according to claim 1, wherein said image processing conforming to said format information is executed in such a manner that an index is added for designating an area of validity according to the aspect ratio of each frame in accordance with said format information. 
     
     
       13. The film image input method according to claim 2, wherein said image processing conforming to said format information is executed in such a manner that an index is added for designating an area of validity according to the aspect ratio of each frame in accordance with said format information. 
     
     
       14.
